The Moon by Day
Image Credit: HJP Arnold |
The Moon by Day Some people never notice that the Moon is visible during the day, but it often is. Because the Earth's atmosphere is so bright and blue (from sunlight scattered by aerosol particles) the daytime Moon is also blue and exhibits little contrast. But as these images demonstrate, relatively good pictures can be obtained during the day. The first image was taken in daylight with a normal digital camera attached to a telescope. Image B was taken immediately afterward with the same equipment but using the B & W mode. It was originally of low contrast (insert) but was enhanced using Photoshop so that it resembles a night time shot such as Image C. There is considerable detail in Image B, including Aristarchus, Grimaldi, Gassendi, Schickard and many smaller craters. Arnold commented, A record obtained under optimum circumstances will always be superior to one secured under less favourable conditions and subsequently improved. But it would be interesting to experiment with day time imaging to see how much can be captured in closeup images - a good project for the last two weeks of a lunation!
